A database is provided. FIG. 2 is a diagram for explaining in detail an example of music data stored in the music database 44. As shown in FIG. 2, the music data stored in the music database 44 corresponding to each music output in the karaoke apparatus 10 is, for example, metadata, MIDI data as performance information, and lyrics information. Contains telop data.

  The metadata includes, for example, information such as a song number (song selection number), a song name, a singer name, and a registration date and time as identification information of each song data. The MIDI data is information for performing performance output control of each music piece via the audio processing unit 22, and for example, the type of musical instrument (performance sound) related to performance output corresponding to each of a plurality of tracks or channels. And musical score information that determines the scale and length of the performance sound to be output. The telop data is information for performing lyric character video display control of each song via the video processing unit 20. For example, each of the lyrics of a song (performance song) corresponding to the song data is divided into a plurality of pieces. Block data B01, B02, B03,..., Bnn corresponding to the sections are included.

  The block data B01, B02, B03,..., Bnn include, for example, display data and attribute data, respectively. This display data includes, for example, coordinates, a color code before change, a color code after change, and a character string. The coordinates define coordinates (for example, xy coordinates corresponding to the upper left corner of the lyrics character image display position) at which the lyrics character image in each block is displayed in the screen of the display 30. The pre-change color code defines a character color (character color of a lyrics character image initially displayed on the screen) before color change by color change display control (wipe) indicating a singing point. The post-change color code defines a character color after color change by color change display control. The character string is text data corresponding to a lyric character image in each block. The attribute data includes a display step, an erasing step, a plurality of (for example, 5 to 10 in one block data) changing steps C01, C02, C03,..., Cmm, and changing speeds corresponding to the changing steps. Is included. The display step determines the timing at which the lyrics character image in each block is displayed on the screen. The erasing step determines the timing at which the lyric character video in each block is erased from the screen. The change step determines a color change timing (color change start timing) indicating a singing point of the lyric character video in each block, and the color change display control of the lyric character video is performed at a corresponding change speed from the timing. It is shown that. The lyric character images displayed on the screen of the display 30 are sequentially changed in color at the timing and change speed determined by the change steps C01, C02, C03,. In other words, the change step determines the change speed of the color change of the lyric text image in each block and the change timing of the change speed.

  FIG. 3 is a conceptual diagram for explaining the basic concept of lyrics character image display control (lyric telop reproduction) by the karaoke apparatus 10. As shown in FIG. 3, in the musical performance output by the karaoke apparatus 10, the lyrics character image corresponding to each block data according to the musical performance progression (increment of the pronunciation step value) based on the MIDI data. Display control is performed, and lyrics color change display control (wipe) is performed in which the lyric character image is sequentially changed in color according to the progress of performance of the music. That is, the lyric character image corresponding to each block data is displayed in the screen of the display 30 in the display step (indicated by a black circle), and the lyric character image is displayed in the changing step (indicated by a gray circle). The color is sequentially displayed in accordance with the changing speed, and is erased from the screen of the display 30 in the erasing step (indicated by a white circle). In the example shown in FIG. 3, the range from the display step to the erasure step in the blocks B03 and B04 partially overlaps, but this is a lyric character corresponding to each of the blocks B03 and B04 in the screen of the display 30. This indicates that there is a time zone in which images are displayed simultaneously.

  In the music data, the change step and the change speed in the block data are predetermined based on the performance progress of the music. That is, regarding the color change display control of the lyric character image, the color change point (boundary between the character color before the change and the character color after the change) in the lyric character image is the singing point (accompaniment sound output) (Position) is predetermined. In other words, the change step and the change speed in the block data are different from the part after the singing point in the portion before the singing point in the lyric character image according to the temporal transition of the singing point of the music. Are sequentially determined so that the colors are sequentially displayed.

  As described above, in the music data shown in FIG. 2, the lyric character video color change display control is performed based on the change step corresponding to the time data and the change speed corresponding to the speed data. Other modes are also conceivable as data serving as a reference for color change display control. For example, the color change display control may be performed based on time data and coordinate data corresponding to the time. Specifically, color changing points (relative positions or corresponding characters in the lyric text image) corresponding to each time point are determined in advance every predetermined time, and at each time point corresponding to the progress of the music performance. Color change display control of the lyrics character image may be performed at the corresponding color change point. That is, as the way of holding the data for performing the color change display control of the lyric character video, the time data and the speed data can be considered as the first mode, the time data and the coordinate data can be considered as the second mode. In the first mode, the amount of data is smaller than that in the second mode, but the error in the color change display control (the difference between the color change point and the singing point) tends to be relatively large. On the other hand, in the second mode, an error in the color change display control is reduced as compared with the first mode, but the data amount is increased.

  FIG. 4 is a functional block diagram for explaining a main part of the control function functionally provided in the CPU 12 of the karaoke apparatus 10. The performance output control means 48 shown in FIG. 4 controls the performance output of music by the karaoke apparatus 10. Specifically, music data corresponding to the music number (music selection number) of the music stored in the reserved music table in order from the upper reserved music in the reserved music table such as the RAM 16 (that is, in the order of input) is stored in the hard disk 18. The music performance output of the music is controlled based on the performance information included in the music data. For example, on the basis of MIDI data as performance information, the sound processing unit 22 outputs performance sounds (music information) of musical instruments corresponding to tracks or channels as musical score information in the MIDI data, and the audio output terminal 36 and Output from a speaker (not shown) via an amplifier 38 or the like.

  The lyric character video display control means 50 displays the lyric character video of the music based on the telop data (lyric information) included in the music data related to the performance output when the performance output control means 48 outputs the music. Take control. That is, a lyric character image corresponding to a character string included in the telop data is generated, and the lyric character image is displayed on the display 30 via the image processing unit 20. Specifically, the lyric character image corresponding to each block data included in the telop data is displayed at the specified coordinates on the display 30 in the display step defined in the block data, and in the erasing step. Control to erase from the screen of the display 30 is performed.

  The lyric character image display control means 50 includes lyric color change display control means 52. This lyric color change display control means 52 basically uses the lyric character video display control means 50 to display the lyric character video displayed on the screen of the display 30 by the performance output control means 48. In accordance with the control, the display is sequentially changed in color. Specifically, the lyric character image corresponding to each block data included in the telop data is changed from the character color corresponding to the pre-change color code based on the change step and change speed defined in the block data. Control is performed to sequentially change the character color corresponding to the rear color code.

  FIG. 5 is a diagram showing an example of color change display control of lyrics character video by a conventional lyrics character video display control device, and FIG. 6 is a diagram conceptually showing a change in character color in the color change display control. is there. In the lyric character image color change display control by the conventional lyric character image display control device, for example, as shown in FIG. 5, it is displayed on the front side of the character background 62 (not necessarily displayed, the same in the following description). The character color of the lyric character image 60 changes from the character color before the change to the character color after the change with the singing point (accompaniment sound output position) 64 to be sung as a boundary as the music performance progresses ( Wipe) That is, in the example shown in FIG. 5, when the lyric character image 60 is initially displayed on the screen, the entire lyric character image 60a corresponds to the character color before the change. The color change display control is started from the left end toward the paper surface, and the lyric character image 60b corresponding to the changed character color is gradually changed toward the right end as the music performance progresses. This color change display control is preferably realized by combining and displaying the lyric character image 60b in a predetermined number of dots on the front side of the previously displayed lyric character image 60a. Note that FIG. 5 and the drawings used in the following description exemplify a lyric character image that corresponds to the Mincho font and is bordered with a color different from the character body. In such an aspect, in the color change display control, it is preferable that both the color of the character body and the color of the border are changed, but if the color change point can be clearly determined visually. Only one of the character main body and the border may be changed in color. This is the same in the following description.

  In the lyric character image color change display control by the conventional lyric character image display control device described with reference to FIGS. 5 and 6, the lyric corresponding to the color change display portion of the lyric character image 60, that is, the character color before the change. A singing point 64 is shown at the boundary between the character image 60a and the lyric character image 60b corresponding to the changed character color. However, it is not always easy to perform a correct singing at the timing of such color change display. Especially for music that is not used to singing, music that is relatively fast or slow, music that speeds up or slows down in the music, etc. However, there are cases where it cannot be understood what utterance (pronunciation) corresponds to the boundary between the lyrics character images 60a and 60b, and it is often difficult to sing smoothly.

  In the present embodiment, the lyric color change display control means 52 includes a preceding point calculation means 54 and a preceding partial color change display control means 56, and in the lyric character image displayed by the lyric character image display control means 50. The color change display control indicating the singing point to be sung at present, that is, the color change display control described above with reference to FIGS. 5 and 6, and the preceding partial color change display control means 56 singing after the singing point. Control to change the color of the preceding part to be performed. In other words, regarding the lyric character image corresponding to the character color before the change relating to the color change display control indicating the singing point, the second color change display control in a mode different from the color change display control indicating the singing point is performed. Do. Further, the form of color change display control of the preceding portion is changed according to the performance progress speed of the music. About this change of a form, a several aspect is later mentioned using FIGS.

  The preceding point calculating means 54 calculates a preceding point preceding the singing point in the lyric character image, and the preceding part includes the singing point in the lyric character image and the preceding point preceding the singing point. Corresponds to the part between. That is, the preceding partial color change display control means 56 is preferably color change display control of the lyrics character video between the singing point in the lyrics character video and the preceding point calculated by the preceding point calculation means 54. I do.

  In the aspect which performs the color change control which shows the said singing point based on time data and speed data, the said advance point calculation means 54, Preferably the time which concerns on the color change control which shows the said singing point from the predetermined relationship The preceding point is calculated based on the data and the speed data. Moreover, in the aspect which performs the color change control which shows the said song point based on time data and coordinate data, Preferably, based on the time data and coordinate data which concern on the color change control which shows the said song point from the predetermined relationship To calculate the preceding point. That is, the preceding point is calculated based on information defining a color change display point (a boundary between the character color before change and the character color after change) related to the color change control indicating the singing point.

  The preceding point calculating means 54 preferably calculates the preceding point so that the distance between the singing point and the preceding point can be changed according to the performance progress speed of the music. Preferably, the preceding point is calculated so that the distance between the singing point and the preceding point becomes longer as the performance progress speed of the music increases. Here, the performance progress speed of the music corresponds to, for example, the tempo (Tempo) of the MIDI data included in the music data, and it can be said that the performance progress speed of the music is faster as the tempo is faster. For example, when “Tempo” in MIDI data represents the number of beats per minute, “Tempo = 60” represents 1 beat per second, and “Tempo = 120” represents 2 beats per second. Therefore, it can be considered that the performance progress speed of the music corresponds to the value of “Tempo” in the MIDI data. The preceding point calculation means 54 preferably calculates the preceding point based on the value of “Tempo” in the MIDI data.

  7 to 9 are diagrams for explaining one aspect of the color change display control of the preceding portion. FIG. 7 shows a case where the performance progress speed of the music is relatively high, and FIG. An example of the color change display control in the slow case is shown respectively, and FIG. 9 conceptually shows a change in the character color in the color change display control. As shown in these figures, the preceding portion color change display control means 56 is preferably a lyric character image 70 displayed on the front side of a character background 72 as one aspect of the preceding portion color change display control. The color from the singing point 74 to the preceding point 76 is changed to a color different from any of the part before the singing point 74 and the part after the preceding point 76. In other words, the portion after the preceding point 76 (the portion on the right side of the drawing) corresponds to the first character color (the character color before the change), and the portion before the singing point 74 (toward the drawing). The left portion) is the lyric character image 70b corresponding to the second character color, and the lyric character image 70c corresponding to the third character color is between the singing point 74 and the preceding point 76. The lyric character image 70 is displayed in different colors in accordance with the progress of the musical performance (transition of singing points). The third character color is preferably an intermediate color between the first character color and the second character color. Such color change display control is performed by, for example, a lyric character image 70a corresponding to the first character color as shown in FIG. 10, a lyric character image 70b corresponding to the second character color as shown in FIG. 12 and a lyric character image 70c corresponding to the third character color as shown in FIG. 12 is generated in advance and stored in the buffer, and the lyric character images 70a, 70b, 70c are, for example, a predetermined number of change dots. It is suitably realized by synthesis or the like (the same applies in the following description).

  In the example shown in FIGS. 7 and 8, when the lyric character image 70 is initially displayed on the screen, the entire range is the lyric character image 70a corresponding to the first character color, or the lyric characters The lyric character image 70c corresponding to the third character color is from the left end of the image 70 to the position corresponding to the preceding point 76. As the performance of the music progresses, the color change display control is started from the left end of the lyric character image 70 toward the paper surface, and the second character color is sequentially turned to the right end according to the transition of the singing point 74. It is changed to the lyric character image 70b corresponding to. The range corresponding to the third character color moves to the right side according to the transition of the singing point 74 without changing the width (the width in the left-right direction toward the page), unless the performance speed is changed. (Slide movement). Further, when the performance progress speed is changed, the width is changed in conjunction with the transition of the singing point 74. That is, the color change display control shown in FIG. 7 and FIG. 8 is actually an animation mode in which two color change changes follow each other (it seems to be separated in a fast scene and catch up in a slow scene). Become. When the singing point 74 reaches the right end of the lyric character image 70 as viewed in the drawing, the range corresponding to the third character color disappears.

  As described above, the preceding point calculation means 54 preferably calculates the preceding point 76 so that the distance between the singing point 74 and the preceding point 76 increases as the performance progress speed of the music increases. Therefore, as shown in comparison with FIGS. 7 and 8, the range of the lyrics character image 70c corresponding to the third character color becomes wider as the performance progress speed of the music increases. In other words, in the modes shown in FIGS. 7 to 9, the lyrics character image 70 a corresponding to the first character color corresponding to the singing point 74 is changed to the lyrics character image 70 b corresponding to the second character color. The color change display control is performed, and the progression speed (performance output speed) of the music is reflected in the range of the lyric character image 70c corresponding to the third character color (width in the left-right direction as viewed in the drawing). Therefore, for example, even if it is a song that does not know the speed of the song, such as a song that is sung for the first time, the singer can determine the progress speed of the song by referring to the range of the lyrics character image 70c corresponding to the third character color. It can be grasped in a visually comprehensible manner.

  FIGS. 13 to 15 are diagrams for explaining another aspect of the color change display control of the preceding portion. FIG. 13 shows a case where the musical performance progress speed is relatively fast, and FIG. 14 shows a musical performance progress speed. An example of color change display control in a relatively slow case is shown, respectively, and FIG. 15 conceptually shows changes in character color in the color change display control. As shown in these drawings, the preceding portion color change display control means 56 is preferably a lyric character image 80 displayed on the front side of a character background 82 as one aspect of the preceding portion color change display control. The color from the singing point 84 to the preceding point 86 is displayed in a color different from the portion after the preceding point 86, and the area of the color changing range gradually decreases from the singing point 84 toward the preceding point 86. It is something to be made. Preferably, as shown in FIG. 13 and FIG. 14, the lyrics character image 80 b corresponding to the character color after the range of the upper left half changes from the singing point 84 to the preceding point 86 corresponding to the character color on the paper surface, The lyrics character image 80 is displayed in a color-changed manner according to the progress of the performance of the music (the transition of the singing points) so that the lower half range is the lyrics character image 80a corresponding to the character color before the change. 13 and 14, the upper left half area between the singing point 84 and the preceding point 86 is the lyric character image 80 b corresponding to the character color after the same change as the part before the singing point 84. The third character color is different from any of the portion before the singing point 84 and the portion after the preceding point 86 between the singing point 84 and the preceding point 86. The color change range may be gradually reduced from the singing point 84 toward the preceding point 86.

  In the example shown in FIGS. 13 and 14, when the lyric character image 80 is initially displayed on the screen, the entire range is the lyric character image 80a corresponding to the character color before the change, or the lyric character The upper left half area from the left end of the image 80 to the position corresponding to the preceding point 86 is the lyric character image 80b corresponding to the changed character color. As the performance of the music progresses, the color change display control is started from the left end of the lyrics character image 80 toward the paper surface, and the character color after the change sequentially toward the right end according to the transition of the singing point 84. It is changed to the lyric character image 80b corresponding to. The range where the preceding portion, that is, the upper left half is the lyric character image 80b corresponding to the character color after the change and the lower right half is the lyric character image 80a corresponding to the character color before the change is a performance progress speed. As long as the singing point 84 does not change, the width (width in the left-right direction toward the paper surface) is not changed, and is moved to the right side (sliding) according to the transition of the singing point 84. Further, when the performance progress speed is changed, the width is changed in conjunction with the transition of the singing point 74. When the singing point 84 reaches the right end of the lyric character image 80 as viewed in the drawing, the range corresponding to the preceding portion disappears.

  As described above, the preceding point calculation means 54 preferably calculates the preceding point 86 so that the distance between the singing point 84 and the preceding point 86 becomes longer as the performance progress speed of the music increases. Therefore, as shown in comparison with FIG. 13 and FIG. 14, the preceding portion, that is, the upper left half is the lyric character image 80b corresponding to the character color after the change, and the lower right half is the character color before the change. The range designated as the corresponding lyric character image 80a becomes wider as the performance progress speed of the music increases. In other words, in the modes shown in FIGS. 13 to 15, the lyric character image 80 a corresponding to the character color before the change corresponding to the singing point 84 is changed to the lyric character image 80 b corresponding to the character color after the change. The color change display control is performed, and the progress speed (performance output speed) of the music is reflected in the range of the preceding portion (width in the left-right direction as viewed in the drawing). That is, the higher the performance progress speed of the music, the gentler the gradient of the oblique lines that divide the lyrics character images 80a and 80b and the respective character color ranges. Therefore, for example, even if the speed of the song is unknown, such as a song that is sung for the first time, the singer can grasp the progress speed of the song in a manner that is easy to understand visually by referring to the range of the preceding part. Can do.

  16 to 18 are diagrams for explaining another aspect of the color change display control of the preceding portion. FIG. 16 shows a case where the performance progress speed of the music is relatively high, and FIG. 17 shows a performance progress speed of the music. FIG. 18 conceptually shows changes in the character color in the color change display control. As shown in these drawings, the preceding part color change display control means 56 is preferably a lyric character image 90 displayed on the front side of a character background 92 as one aspect of the preceding part color change display control. In the preceding part to be sung after the singing point 94, the color density gradually changes from the singing point 94 in the direction of color change (in the example shown in FIGS. 16 and 17 to the right in the drawing). Display gradation (gradation). That is, the portion after the singing point 94 (the portion on the right side of the drawing) corresponds to the gradation display, and the portion before the singing point 94 (the portion on the left side of the drawing) has the changed character color. The corresponding lyrics character image 90b is used. The preceding partial color change display control means 56 changes the gradation display mode in accordance with the performance progress speed of the music. Preferably, the gradation display changes so that the change in density difference becomes gentle (soft) as the performance progress speed of the music increases, and the change in density difference becomes steep (hard) as the performance progress speed slows down. Change the aspect. In other words, the gradation display mode is changed so that the section where the gradation can be visually confirmed becomes longer as the performance progress speed of the music increases. The gradation display mode is such that the change in density difference becomes steeper (hard) as the performance progress speed of the music increases, and the change in density difference becomes gentle (soft) as the performance progress speed slows down. It may be changed.

  In the example shown in FIGS. 16 and 17, when the lyric character image 90 is initially displayed on the screen, the entire range is a lyric character image 90a corresponding to gradation display. That is, a gradation display is applied in which the end portion on the left side of the lyric character image 90 is the darkest and the character color gradually becomes lighter toward the right side. As the performance of the music progresses, the color change display control is started from the left end of the lyric character image 90 with respect to the paper surface, and the character color after the change sequentially toward the right end according to the transition of the singing point 94. It is changed to the lyric character image 90b corresponding to. Here, in the example shown in FIGS. 16 and 17, the color change from the lyric character image 90a corresponding to the gradation display accompanying the transition of the singing point 94 to the lyric character image 90b corresponding to the character color after the change is not performed. The border color of the lyric character image 90 is changed, and the character color of the character body is smoothly changed from the lyric character image 90a corresponding to the gradation display to the lyric character image 90b corresponding to the changed character color. They are connected (see FIG. 18). That is, preferably, the character color of the character body in the lyric character image 90b corresponding to the changed character color is the character body of the portion corresponding to the singing point 94 in the lyric character image 90a corresponding to the gradation display. Equal to text color. When the performance progress speed changes, the gradation display in the lyrics character image 90a is changed in conjunction with the transition of the singing point 74. When the singing point 94 reaches the right end of the lyric character image 90 in the drawing, the range corresponding to the preceding portion disappears.

  As described above, the lyric character image 90a corresponding to the gradation display has a change in the density difference as the performance progress speed is slow so that the change in the density difference becomes gentle (soft tone) as the performance progress speed of the music increases. The display mode is changed so as to become steep (high contrast). Therefore, as shown in comparison with FIG. 16 and FIG. 17, the higher the performance progress speed of the music, the wider the darker range, and the longer the section where the gradation can be visually confirmed in the preceding portion. In other words, in the modes shown in FIGS. 16 to 18, color change display control from the lyrics character image 90 a to the lyrics character image 90 b corresponding to the changed character color is performed corresponding to the singing point 94. At the same time, the progression speed (performance output speed) of the music is reflected in the gradation display range (width in the left-right direction with respect to the paper surface) in the preceding portion. Therefore, for example, even if the speed of the song is unknown, such as a song that is sung for the first time, the singer can grasp the progress speed of the song in a manner that is easy to understand visually by referring to the range of the preceding part. Can do. In such an aspect, it is not necessary to calculate the preceding point by the preceding point calculating means 54.

  19 and 20 are diagrams for explaining a modification example of the color change display control of the preceding portion described above with reference to FIGS. 7 to 9. FIG. 19 is a diagram when the performance progress speed of the music is relatively fast. Reference numeral 20 denotes an example of color change display control when the performance progress speed of the music is relatively slow. As shown in these drawings, the preceding part color change display control means 56 is preferably a character background displayed on the back side of the lyrics character image 70 as one aspect of the color changing display control of the preceding part. 72 between the singing point 74 and the preceding point 76 may be displayed in a different color from the part before the singing point 74 and the part after the preceding point 76. In other words, the character background 72a in which the portion after the preceding point 76 (the portion on the right side of the drawing) and the portion before the singing point 74 (the portion on the left side of the drawing) correspond to the first character color, the singing Lyric character image including the character background 72 in accordance with the progress of performance of the music (transition of singing points) so that the character background 72b corresponding to the second character color is between the point 74 and the preceding point 76. 70 color change display control may be performed.

  FIG. 21 is a flowchart for explaining a main part of an example of the musical performance output control by the CPU 12 of the karaoke apparatus 10 and is repeatedly executed at a predetermined cycle.

  First, in step (hereinafter, step is omitted) S1, an input of a music selection number by an input operation of the operation panel 24 or an electronic quick sample apparatus (not shown) is accepted. Next, in S2, it is determined whether or not there has been a music selection operation (input of music selection number) for selecting and inputting a predetermined music. If the determination in S2 is negative, the processing from S1 onward is executed again. If the determination in S2 is positive, in S3, the performance output of the selected music is started. The process of S3 may start performance output of the music registered in the reserved music table such as the RAM 16. Next, in S4, music data corresponding to the music for which performance output is started is read from the music database 44 and developed in the RAM 16 or the like. Next, in S5, MIDI / telop parallel processing based on the MIDI data and telop data in the music data read in S4 is started, and telop reproduction processing (described later with reference to FIG. 22) in SA and MIDI reproduction in SB. Processing is performed in parallel. Next, in S6, the MIDI / telop parallel processing is terminated, and this routine is terminated accordingly. The MIDI playback process in the SB is a well-known MIDI data playback process, and detailed description thereof is omitted in this embodiment.

  FIG. 22 is a flowchart (subroutine) for explaining a main part of an example of the telop reproduction process SA in the music performance output control of FIG. 21, and the preceding portion color change display control described above with reference to FIGS. It corresponds to. In this control, block data Bn (block data following the previously read block data Bn-1) is read at SA2 following the processing loop start end SA1 of the block data B01 to Bnn in the telop data, and the audio The processing unit 22 compares with the step value related to the MIDI performance output. Next, in SA3, it is determined whether or not the display step is determined in the attribute data of the block data Bn. If the determination of SA3 is negative, the processing from SA8 is executed. If the determination of SA3 is positive, blocks corresponding to the lyrics character images 70a, 70b, and 70c, respectively, in SA4. An image (see FIGS. 10-12) is generated and stored in the buffer. Here, the character color of the lyric character image 70c is preferably determined from the character color of the lyric character image 70a (color code before change) and the character color of the lyric character image 70b (color code after change). An intermediate color code is calculated and used. Next, in SA5, the pre-change block image, that is, the lyric character image 70a corresponding to the first character color is displayed on the screen of the display 30 via the image processing unit 20 or the like. Next, in SA6, it is determined whether or not the MIDI data performance output (MIDI performance) in the audio processing unit 22 has been completed. If the determination of SA6 is affirmed, it is returned to the music performance output control shown in FIG. 21, but if the determination of SA6 is negative, the block data B01 to Bnn in the telop data are returned. The process is returned to SA1 through the processing loop end SA7, and the processes after SA2 are executed again.

  In SA8, it is determined whether or not the change step is determined in the attribute data of the block data Bn. If the determination at SA8 is negative, the processing from SA11 is executed. If the determination at SA8 is affirmative, in SAA, the lyrics character image 70b corresponding to the second character color is related. The change dot number calculation process shown in FIG. 23 is executed. Regarding the SAA processing relating to the lyrics character image 70b corresponding to the second character color, the added value α = 0. That is, the calculation process of the change dot number which concerns on the color change display control corresponding to a change step (singing point 74) is performed. Next, in SA9, the display of the lyric character image 70b is updated corresponding to the number of change dots calculated in SAA for the lyric character image 70b corresponding to the second character color, and the lyric character image 70 is updated. Color change display control indicating the singing point 74 is executed. Next, in SAA, the calculation process of the number of changed dots shown in FIG. 23 is executed for the lyrics character image 70c corresponding to the third character color. Regarding the SAA processing relating to the lyrics character image 70c corresponding to the third character color, the added value α = 100. That is, the calculation process of the number of change dots related to the color change display control corresponding to the portion between the change step (singing point 74) and the preceding point preceding the change step is performed. Next, in SA10, the display of the lyric character image 70c is updated corresponding to the number of change dots calculated in SAA for the lyric character image 70c corresponding to the third character color, and the lyric character image 70 is updated. After the color change display control of the preceding part is executed, the process after SA6 is executed. In SA11, it is determined whether or not it is an erasing step determined in the attribute data of the block data Bn. If the determination at SA11 is negative, the processing below SA6 is executed. If the determination at SA11 is affirmative, the screen of the display 30 is displayed via the video processing unit 20 or the like at SA12. After the lyric character image 70, which is the display block displayed on the screen, is erased, the processing from SA6 onward is executed.

  FIG. 23 is a flowchart (subroutine) for explaining a main part of an example of the change dot number calculation process SAA in the telop reproduction process of FIG. In this control, first, Tmp is initialized in SAA1, and Tmp = 0 is set. Next, in SAA3 following the processing loop start SAA2 of the attribute data change steps C01 to Cmm in the block data, the change step value and the change speed value corresponding to the change step value are extracted. Next, in SAA4, it is determined whether or not the step value related to the performance step, that is, the performance output based on MIDI data, is smaller than the change step value extracted in SAA4. When the determination of SAA4 is negative, after the number of changed dots is set to Tmp as a processing result in SAA7, the processing is returned to the telop reproduction processing shown in FIG. 22, but when the determination of SAA4 is affirmed. In SAA5, Tmp is calculated based on the performance step value, the change step value, and the change speed value. That is, ((performance step value + α) −change step value) × change speed value is added to Tmp. Next, the process returns to SAA2 through the processing loop end SAA6 of the change steps C01 to Cmm in the block data, and the processes after SAA3 are executed again.

  As described above, in the control described with reference to FIGS. 21 to 23, SB is the processing of the performance output control means 48, SA is the processing of the lyrics character video display control means 50, and SAA and SA9 are the lyrics color change display. SAA corresponds to the processing of the control means 52, SAA corresponds to the processing of the preceding point calculation means 54, and SAA and SA10 correspond to the processing of the preceding partial color change display control means 56, respectively. Further, the telop reproduction process shown in FIG. 22 and the change dot number calculation process shown in FIG. 23 correspond to the lyrics character image display method of the present embodiment.

  Thus, according to the present embodiment, in the lyric character image 70 and the like, the color change display control indicating the singing point 74 and the like to be sung at the present time is performed, and the singing point 74 and the like should be sung later. Since the color change display control of the preceding part is performed and the form of the color change display control of the preceding part is changed according to the performance progress speed of the music, the progress speed of the music is By reflecting in the color change display of the lyrics character image 70 etc. after the point 74 etc., even if it is a music whose speed of the music is not known, such as a music to be sung for the first time, etc. Can let the singer grasp. In other words, the change of color change of the lyrics character image 70 and the like is made into two stages, and the future position up to the point that precedes the output position of the accompaniment sound is superimposed and displayed, thereby singing the speed of singing at each time point. Can be made to grasp. That is, it is possible to provide the karaoke apparatus 10 as a lyric character image display control device that realizes lyric character image display control that is easy to sing.

  The preceding portion corresponds to a portion between the singing point 74 etc. and the preceding point 76 etc. preceding the singing point 74 etc. in the lyrics character image 70 etc., and the singing point 74 etc. and the preceding point 76. Since the distance to the song can be changed according to the performance progress speed of the music, the progress speed of the music is changed to the length of the color change display portion of the lyrics character image 70 etc. after the current singing point 74 etc. By reflecting it, it is possible to make the singer grasp the progress speed of the song in a visually easy-to-understand manner.

  The preceding portion corresponds to a portion between the singing point 74 etc. and the preceding point 76 etc. preceding the singing point 74 etc. in the lyrics character image 70 etc., and the preceding point 76 etc. is determined in advance. Since it is calculated based on the time data and speed data related to the color change control indicating the singing point 74 and the like from the determined relationship, the progress of the song is performed using the practical data provided in the conventional song data. The speed can be reflected in the length of the color change display portion of the lyrics character image 70 and the like after the current singing point.

  The preceding portion corresponds to a portion between the singing point 74 etc. and the preceding point 76 etc. preceding the singing point 74 etc. in the lyrics character image 70 etc., and the preceding point 76 etc. is determined in advance. Since it is calculated based on the time data and coordinate data related to the color change control indicating the singing point 74 and the like from the determined relationship, the progress of the song using the practical data provided in the conventional song data The speed can be reflected in the length of the color change display portion of the lyrics character image 70 and the like after the current singing point.

  Further, since the distance between the singing point 74 and the preceding point 76 is changed so as to increase as the performance progress speed of the music increases, the progress speed of the music is changed from the current singing point 74 and the like. By reflecting on the length of the color-change display portion of the lyric character image 70 or the like, it is possible to make the singer grasp the progress speed of the song in a visually easy-to-understand manner.

  In addition, in the color change display control of the preceding part, the color between the singing point 74 and the preceding point 76 is changed to a color different from the part before the singing point 74 and the part after the preceding point 76. Therefore, the progress speed of the music can be reflected in a color-changed display of the lyrics character image 70 after the current singing point 74 in a practical and visually easy-to-understand manner.

  In addition, the color change display control of the preceding part is performed by changing the color between the singing point 84 and the preceding point 86 to a color different from the part after the preceding point 86, and from the singing point 84. Since the color change range is gradually reduced toward the preceding point 86, the progress speed of the music can be displayed practically and visually easily in the color change display of the lyrics character image 80 after the current singing point 84. Can be reflected.

  In addition, the CPU 12 of the karaoke apparatus 10 performs color-change display control indicating the singing point 74 to be sung in the lyric character image 70 or the like, and precedes the singing point 74 or the like before being sung. The color change display control of the part is performed, and it is made to function as the lyric character image display control means 50 (SA) for changing the form of the color change display control of the preceding part according to the performance progress speed of the music. Since it is a characteristic lyric character image display control program, by reflecting the progress speed of the tune on the color change display of the lyric character image 70 after the current singing point 74, etc. Even if the music does not know the speed, it is possible to make the singer grasp the progress speed of the music in a visually easy-to-understand manner. That is, it is possible to provide a lyric character image display control program that realizes lyric character image display control that is easy to sing.

  Further, in the lyric character image 70 and the like, color change display control indicating the singing point 74 to be sung at present is performed, and color change display control of a preceding part to be sung after the singing point 74 and the like is performed. Since it is a lyric character image display method that changes the form of color change display control of the preceding portion according to the performance progress speed of the music, the progress speed of the music is changed from the current singing point 74 and the like. By reflecting on the color change display of the lyrics character image 70, etc., even if the song speed is not known, such as a song that is sung for the first time, the singer grasps the progress speed of the song in a visually easy-to-understand manner. Can be made. That is, it is possible to provide a lyric character image display method that realizes lyric character image display control that is easy to sing.

  The preferred embodiments of the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to these embodiments, and may be implemented in other modes.

  For example, in the above-described embodiment, the example in which the present invention is applied to the lyric character image 70 or the like displayed on the display 30 has been described. However, the present invention is not limited to this, for example, the karaoke apparatus The present invention is also suitably applied to display control of lyric character images displayed on a touch panel display provided in the 10 main body (commander main body) and display control of lyric character images displayed on an electronic quick sample device as an input device. It is what is done.

  Moreover, although the above-mentioned Example demonstrated the example in which this invention was applied to the lyric character image display control by the karaoke apparatus 10 which is the communication karaoke apparatus installed in stores, such as a karaoke box, and was connected to the communication line 42. Lyric character video display control by a non-communication karaoke device not connected to a communication line, lyric character video display control when a mobile phone is used as a karaoke device, or lyric characters in a karaoke function as application software in a so-called consumer game machine The present invention is also preferably applied to video display control.

  In the above-described embodiment, the preceding point 76 and the like are calculated based on time data and speed data related to the color change control indicating the singing point 74 and the like from a predetermined relationship, and the preceding point 76 and the like are preceded by the preceding point.
